From a straightforward gas boiler swap to a full oil-to-gas conversion, we provide every boiler replacement service a Long Island homeowner or business could need. All work is performed by a licensed master plumber and backed by manufacturer warranties.
Every service we offer is performed by a licensed master plumber, covered by manufacturer warranties, and backed by over four decades of experience on Long Island.
The most common service we perform. Whether you are replacing an aging gas boiler or upgrading to a high-efficiency condensing unit, we handle the full installation including venting, piping, and gas connections. Available in cast iron, wall-hung, and combi configurations.
Learn MoreSuffolk County and parts of Nassau still rely on oil heat. We install high-efficiency oil-fired boilers from brands like System 2000 and Williamson that deliver significant fuel savings over older units. Includes burner setup, tank connections, and chimney liner evaluation.
Learn MoreSteam systems require specialized knowledge that many contractors lack. Proper sizing depends on measuring the total radiation in the home, not the output of the old boiler. We have been working on Long Island steam systems for over 45 years and understand the nuances of one-pipe and two-pipe configurations.
Learn MoreHot water baseboard systems are common throughout Long Island, particularly in homes built from the 1960s onward. We replace failing hot water boilers with properly sized modern units, including zone valve replacement and system flushing when needed to ensure optimal performance.
Learn MoreCombination boilers provide both space heating and domestic hot water from a single compact unit, eliminating the need for a separate water heater. Ideal for smaller homes or where mechanical room space is limited. We install wall-hung combi boilers from Navien, Bosch, and Buderus.
Learn MoreWe serve commercial properties across Long Island including apartment buildings, office spaces, retail locations, and houses of worship. Commercial installations require careful load calculations, compliance with local codes, and minimal disruption to building occupants. We coordinate scheduling to meet your operational needs.
Learn MoreOne of the most impactful upgrades a Long Island homeowner can make. We manage the complete conversion process: coordinating with National Grid for gas service, removing the oil boiler, installing a new gas unit, upgrading the venting, and assisting with oil tank decommissioning. Typical projects take two to three days.
Learn MoreWhen your boiler fails in the middle of winter, you need a contractor who can respond immediately. We prioritize emergency replacements during the heating season and stock common boiler models to enable same-day or next-day installation. Based in Melville, we can reach any location on Long Island quickly.
Learn MoreBeyond standard boiler replacement, we offer specialized services to help Long Island homeowners make informed decisions about their heating systems.
New construction and first-time boiler installations with proper system design.
Electric boiler options for properties without gas or oil service.
Transitioning from boiler heat to a modern heat pump system.

Every boiler replacement follows a structured process designed to ensure quality work, transparent pricing, and a smooth experience from start to finish.
A technician visits your home, inspects your current system, measures radiation output (for steam), evaluates your distribution, and discusses your needs and budget. No charge, no obligation.
You receive a detailed written quote that includes the equipment, labor, permit fees, and any additional work required. The price we quote is the price you pay. No hidden fees or surprise charges.
We pull the required permit, schedule the work, and complete the installation. Most residential replacements are finished in a single day. We protect your home and clean up completely when we are done.
The local building department inspects the work to verify it meets code. We walk you through your new system, register the manufacturer warranty, and submit any applicable rebate paperwork on your behalf.
We are factory-trained on all 11 brands and can recommend the right manufacturer for your system type, budget, and performance requirements.
We have built our reputation one boiler at a time over 45 years. Here is what Long Island homeowners have to say about working with us.
"Our boiler died on a Saturday night in January. We called Domino's first thing Sunday morning and they had a new Weil-McLain installed by Monday afternoon. Professional, fair price, and they explained everything clearly. Could not ask for more."
"We had three companies come out to quote an oil-to-gas conversion. Domino's was the only one that actually measured our radiators and took the time to explain why the boiler size matters. Their price was competitive and the work was excellent. Highly recommended."
"I manage a 24-unit apartment building in Hempstead. Domino's replaced our commercial boiler with minimal disruption to the tenants. They handled the permits, coordinated the inspection, and the new system has been running perfectly. These guys know what they are doing."
